我国土源性线虫病监测现状及今后监测工作重点

土源性线虫病在我国农村地区广泛流行。2005年原国家卫生部公布的全国人体重要寄生虫病现状调查结果表明,土源性线虫感染率为19.56%,感染人数达1.29亿。2006年中国疾病预防控制中心将其纳入了全国重点传染病和病媒生物监测体系,在全国建立了22个监测点。2006-2013年监测期间,土源性线虫病国家级监测点人群感染率从20.88%下降至3.12%,呈逐年下降趋势;蛔虫、鞭虫、钩虫、蛲虫感染率分别从2006年的10.10%、5.88%、8.88%、10.00%下降到2013年的0.76%、0.42%、2.04%、6.78%。本文通过对我国土源性线虫病8年监测工作的总结,概述了该病的流行现状,监测工作取得的经验及面临的挑战,同时强调了今后监测工作的重点。

Current situation of soil-transmitted nematodiasis monitoring in China and working keys in future

Soil?transmitted nematodiasis is widely epidemic in rural areas in China. It was showed that the infection rate ofsoil?transmitted nematodes was 19.56% while the overall number of persons infected was 129 000 000，which was supported bythe results of the National Survey of Current Situation of Major Human Parasitic Diseases in China in 2005 published by formerMinistry of Health. Therefore，soil?transmitted nematodiasis was included in the national infectious diseases and pathogenic me?dia monitoring system by Chinese Center for Disease Control and Prevention in 2006，and subsequently 22 monitoring spotswere established nationwide. From 2006 to 2013，the human infection rate of intestinal nematodes in national monitoring spotsdecreased from 20.88% to 3.12%，which showed a declining trend year by year. Meanwhile，the infection rates of Ascaris lumbri?coides，Trichuris trichiura，hookworm，Enterobius vermicularis decreased from10.10%，5.88%，8.88%，10.00% in 2006 to0.76%，0.42%，2.04%，6.78% in 2013 respectively. In this paper，the current situation of soil?transmitted nematodiasis is over?viewed based on a summary of the 8 years’ monitoring work，as well as the experiences，challenges and key of monitoring workin the future.
